In the drawings Fig. 1 is a plan of the keyboard used in the practice of my improvements'in selective mechanism as applied to typographical machines of the class shown and described in Letters Patent No. 436,532 granted September 16,1890, to O.. Mergenthaler; Fig. 2 is a vertical longitudinal sectional view through the keyboard unit of my selective mechanism, taken on line 2-2 of Fig. 1, but including mechanism Anot shown in Fig. 1; Fig. 3 is a vertical longitudinal sectional view taken on line 3-3 of Fig. l; Fig. 4 is an elevational view partly in section showing the switch mechanism of the keyboard unit, the line of section of the parts so shown is on the line 1fof Fig. 5; Fig. 5 is a extension `208 with the bearing element 210 which is removably secured by screws 210 and 210.` The said bearing members removably holds shafts 201 and 207 in their positions in bearings 211 to 217. When itis necessary to remove the shafts 201 to 207 or any of them from their bearings, the bearing plate 210 is removed and the frame member 110 is also removed, and said shafts 101 to 107 and the parts or shafts into which they are soclreted, as stub shafts 201 to 207 may be lifted from their bearings.

Each of the stub shafts 2001 to 207 carries an idle gear as 221 to 227 inclusive, of which the gear 227 is typical, as indicated in Fig. 13'. These gears inter-mesh and run constantly in a train and are driven from gear 227, by any suitable means as gear 228, which is so formed and adjusted as to rotate the gear 227. and suitable driying gear 229.

Said gears 228 and 229 may be bevelled or a pulley may be substituted in the place of gear 228.

It Will be seen that the cam shafts 101 to 107 may remain at rest while the gears 221 to 227 rotate coi'itinuoinstly. To actuate the spring releasing members 1001 to 1090 for ejecting a matrix from the magazine, it is necessary to rotate one or more of the cam rods, or cam shafts 101 to 107. This operation will be presently explained. but in this place it is essential to explain merely the trip mechanism of tbe transnjiission unit, corresponding with the transmission unit shown and described in my previous application,

(Serial No. 39,155).

In this application as in the previous application there are three co-actinn` units, the magazine, or escapement unit, the transmission unit and the keyboard unite. ln the present application the transmission unit is mounted upon and directly connected with the magazine unit and constructed as a part thereof. rlhe cam rods 101 and 107 belonging to the magazine, or escapement unit, as before explained are provided with angular ends .as 101?L to 107 a and said ends are seated in corresponding angular recesses in socket members 201iL tov207n provided upon the ends of stub shafts 201 to 207. The said stub shafts are socketed at their opposite ends 201b to 207b in the idle gears 221 to 227. 'Each of said idle gears has an extension thereon :221.a to227l which is held in bearings provided in the extension 2055 of the frame 10S and the removable plate 2 10.

Upon the stub shaft 207 a clutch member' 237, is splined being one of a seriesof clutc ies 231-to 237, not all shown, and upon the idle gear 227 is a mating clutch 227, When the clutch is in engagement the clutch member 237 is caused to rotate with the rotating idle gear which rotates continuously.

By the means described the stud shaft 207 upon which said clutch member 237 is splined wea/125 is rotated and the cam-rod 107 having its end 107'L seated in the socket member 2.07d of the stub shaft 207 is rotated therewith. Oneor any number of said cam rods 101 to 107 may be rotated when the clutches thereof are thrown into engagemenhso as to actuate the required spring releasing member. For eX- ample; if one clutch only is engaged only the corresponding cam rod will be rotated, but if any two of the clutches are engaged or any three or any other number, are engaged, then the corresponding cam rods will be rotated accordingly.

To engage `the clutches it is necessary to release the trip of the transmission unit 200, which is done by actuating` a ley of the key board unit 300, hereinafter described.

rlhe trip mechanism comprises the splined clutch members 231 to 237 and other parts shown in Fig. 14 ofthe drawings. rl`he clutch member 237 is slidably splined upon the stub shaft 207 and is normally held disengaged from the clutch members of the idle gear 227, by the trip 247 of the series, to which trip is pivoted at 2&7 and has two pawls 2471) and 2l7c thereon. Vlhe pawl 214.7" engages a lug 2 37a o n the clutch member whereby the clutch is held disengagee rlfhe trip is released by touching a key of the heyboard whereby an electric circuit controlling an electromagnet 257, is connected, or closed, said magnet being of a series, 251 to 257, (not all shown). rlhe movement of the magnetic trip overcomes the tension of the spring .s 24.71, of the series, 241d to 2il7l'(1iot all shown) and releases to pawl 247) and at the same time the pawl 247c is moved so as to enter he annular recess or groove 237e of the clutch 287. The spring 267, of the series 201 to 2077 (not all shown) then forces the clutch member 237 towards the idle gear 227, but not fa r enough to engage the clutch. rThis moven'ient is instantaneous and the trip member 2-l7 retained by the magnet only so long as the circuit is closed. When the circuit is broken by the releasal of the lrey of the key board. the trip 2&7 is instantaneously restored by the spring 2117, As soon as the trip is restored to its former position the trip pawl 247C dis engages the groove 23"C and thus the clutches 22"? and 237EL are thrown into engagement by the spring 267. The said clutch member is provided with cam means for diseugagin y the'clutch and stopping the rotation of clutch after a single revolution at the l or normal position thereof, so that the parts after a single rotation instantaneously come to a stop and are in readiness for being again actuated. The said cam means comprises the the cam 237d and the cam roller 277 of the series 271 to 277, (not all shown) and said cam roller is shown in dotted lines and is supported upon a stud 278.

Y

Referring to the drawings formingk a part of vthis specification my improvements in selective mechanism herein described comprises; first, selective cscapement mechanism second,'transm1ss1on mechanism, and third,

keyboard mechanism In the selective escapement the .numeral 100 indicates the magazine unit, and 101 top10 shown, they being numbered 1001 to 1010,

and in Fig. 14, the spring releasing member shown is 1090. The spring releasing member shown in Fig. 8 may be assumed to be 1001. The cam rods 101 to 107 are rotatably heldin bearings in a frame 108 which supports all the parts ot' the selective mechanism of the escapement and transmission mechanism, and comprises the base section 109 and the removable section 110. Atthe left arebearings 111 to 117 inclusive, for the ends of the cam I rods. The opposite ends of the cam rods are non-circular in cross section, as indicated in dotted lines and are removably seated in correspondingly formed sockets 121 to 127 inclusive on the ends of the shafts 201 to 207 inclusive ofthe transmission mechanism.

In the frame section 110 there are two transverse bars 110a and 110" and in the bar 110a are provided slots as 1101u to 1190a,.and in the bar 110b are provided slots 11011 to 1190", in which are seated the respective ends 1001a to 1090El and 1001b to 1090 of the spring releasing members 1001 to 1090.

-Under the transverse bar 110a is a reinovable plate 110c and 'superposedupon the bar 110a is a removable plate 1101. Under the transverse bar 110b is a removable plate 110e,

and superposed upon the bar 110b is a removable plate 110.

Said' removable plates serve to retain the' end s 1001a to 1090 and 1001b to 1090b ot' the spring releasing members 1001 to 1090 in said slots 1101et to 1190 in the bar 11017and slots 1101b to 1190b in the bar 110).

Y lV hen said removablerplates are in assem` bled relation with the said transverse bars construction of the recesses aforesaid, and so` that by removing the superposed plates 1.10d and 110f it is possible to remove any one of the spring releasing members 1001 to 1090, from the'frame by lifting the ends thereof from their respective slots, but when the 'superposed plates aresecured in their positions the spring releasing members are securely held in the slots in the said transverse bars.

' A further member of the frame 108 is the board 1 to 64 inclusive.

all alike 1n form, except where special key by a matrix may be selectively released from its respective usual channel in the magazine by touchmg a key corresponding with such matrix, when such key is depressed, wherever v 611 inclusive, coruiting itrom lett to right; and

second; the blades 301 to 30T inclusive; and thlrd the transmission mechanism herein- 7 before described connected with the magazine unit, and fourth; the selective cam mecha-` nism of the magazine unit.

Each of the key weights is mounted so as to be movable vertically in suitablebearings. (See F ig. 2.) ln the figure key weight 19 is shown, having an upper extension l and a lower extension 19a, which are disposed in suitable guides so that the weights mayo be raised and lowered by the keys ot the keyrThe key weights, are

weights may be made as maybe hereinafter explained. `But the uniform key weights have each a plurality ot recesses as 10c to 19h inclusive, so that they may be used inter-` changeably for the key levers, as l5, 1G, 1T, 18, or 19, and each key weight has a series of extensions thereon as 191, 19H ttc. to 19d for engaging the blades 301 to 307 inclusive or apart ot them according to the key and l the particular combination ot blades actuated by said key. Provision is made however so that each of the key weights will engage, only certain pre-determined selective blades, whereby the required combination ot the blades will be engaged and actuated by each particular weight, when elevated by its respective key. J-rcomplete table ot the combinations hereinafter set forth as a part ot this specification.

lt will be obvious that the portions oit the blades wherethey are cut away cannot be engaged by the extensions or :lie key weights but will be engaged thereby only Where they are not cut away. The object ot this provision is; that `when any ot the blades 301 to are rocked by the ke weights the movement will be transmitted through the transmission unit 200 to the magazine, or escapement unit 100 and so actuate the spring releasing mechanism by means et the cam rods 101 to 107, or certain selective number of the said cam rods in order that the matrix in the channel corresponding with the key by which the-parts were actuated will be released from the magazine. Explanation Jfollows.

l`hus it' one blade only is engaged .by the key weight, `only that one blade will move, and such movement y till be transmitted to but one ot' the rocking rods, or cam rods of the magazine unit 100; but it two ot the blades are engaged by the weight that is actuated then thaty movement will be transmitted to two of the rocking rods or cam rods of the magazine unit.

It should be remembered that the selective process is follows: lyremoving from the blades the part thereof which might be engaged by the iiy gers or extensions ot the key weights when it desired that the movement or the key weight should not actuate the particular blade; and on the other hand, where it is desired to actuate a certain blade by a certain key weight and connecting key the portion ot' the blade contiguous, remains so as to be engaged by the contiguous linger or eX- tension of the key weight adjacent thereto.

To transmit selectively the movement of one of the keys ot the keyboard through the transmission unit to the selective mechanism ot the magazine unit, electrical means is employed to actuate a plurality or electro-magnets hereinbefore described whereby the trip mechanism described is actuated.

The electrical means employed comprises a plurality ol circuit closing switches provided upon and actuated byeach ot the blades 301 to 307, shown in Fig, si and Fig. ot the drawings. i

Each of said blades 301 to 30T has an extension as 311 to 317 and a switch as to 32T, is mounted thereon so that it will be moved in an arc whenever the blade is rocked. The ends of said extensions are angularly formed, and insulating sleeves 331 to 337 are disposed within angular opening in the switcaes, then the sleeve is disposed upon its respective. eX- tension. The said sleeves abut against an insulating plate as 341 to 3M, so that the switches are fully insulated from the keyboard mechanism andthe rocking blades. 'lo each of the switches, is connected a wire as 351a to 357a indicated in dotted lines and communicating with magnets to 257 respectively.

Each of the switches is provided with a spring circuit clos ig element as 371 to 377 whereby the circuit may be closed with but slight movement ot the rocking blades. Each binding posts as 2511 to 257b of the electromagnets. 251 to 257 Fig. 20). .It willv be obvious that when any one of said switches, 321 to 327 contacts with the universal bar 880 said ba-r will be raised so as to Contact with the universal contact 888 so that the electromagnet connected `therewith will be actuated and the trip mechanism thereby reelased so that the corresponding cam rod wil-l be rotated by means of the clutch connected therewith. Accordingly, since the said switches, magnets and trips are designed and adapted to act either singly or in combinations of two to seven units, it will be seen that correspondingly with the number of rocking blades and connected switches that are actuated the connected magnets, trips and clutches, will be actuated singly or in. combinat-ions of twoto seven units.

Thus by the selective mechanism of the keyboard unit, the selective mechanism of the transmission unit or tripping means is selectively actuated, so that the selective cam rods are actuated, singly or in combinations of two to seven, so that by touching a certain key of' the keyboard unit, the required spring releasing member of the magazine unit `is actuated so that a matrix corresponding with the character of the key actuated will be ejected from the magazine. Y

The escapement employedin the selective mechanism may 4now be described. The

spring releasing members 1001 to 1090 are represented in Fig. 8 by the member'numbered 1001 and in Fig. 9 by members 1001 to 1010 inclusive. The said spring membersv are firmly held by extensions as 1001'nl and 1001b in slots in the. frame 108 and are normally held in elevated position against the force or" lthe spring elements 1001c and 1001d as shown in Fig. 8 b'yfoneV or more of the cam rods 101 to 107. In Fig. 8 cam rod 101 is shown holding spring member 1001 in the elevated position. The springmeml'xer 1001is actuated only when cam rod 101 only is actuated. The cam element is lowered by the rotation of the cam rod and there being no other cam element to support the spring member 1001 it is released and lowered by its own springl power.

The escapement pawl 1201 of the series 1201 to 1290 is actuatedby the spring releasing member so as to eject a matrix from the magazine channel controlled thereby.

In case two or more of the cam rods rotate in combination to releasek the spring releasing member each of the cam elements of such combination is 'formed and normally disposed as the cam element of cam rod 101 in Fig. 8, that is to say; it is oblong in cross section and is perpendicular to the plane of the magazine and the said several cam elements always rotate in unison when the spring releasing member thereabove is to be actuated,

- so that each of the cams in the combination Lies-,425

are rotated in unison, thereby permitting the spring releasing member to act.

And again; if all of the said perpendicular cam elements under a spring releasing member are lowered, but one or more of the cam elements such as shown in Fig. 8 in rods 102 to 107 inclusive rotate at the same time, still the spring releasing member cannot act, since thebody of the rod as 102 to 107 one or more of which may be rotated will support the spring releasing member, and prevent it from being lowered by its own spring power.

For example; the cam element of cam rod 101 may be lowered by the rotation of cam rod 101 alone, but if at the same time cam rod 102 or any other, others or all of the other cam rods are rotated the spring releasing member cannot act because it is supported by the peripheral surface and body of such cam rods, one or more, 102 to 107, which lnay be rotated.

The cam element of rod 101 when rotated is at the minimum elevation during 180 degrees of its revolution thus permitting the maximum descent of the releasing member during one half of its revolution. In the case of each of the spring releasing members the cam combinations by which they are controlled must have one or more vofsaid cams normally in engagement therewith, and in all combinations but the one described and shown inthe drawing Fig. 8, there are two or more of such cam elements normally in engagement with thev spring releasing member, and the others in saidpcombination are disengaged normally. The cam elements nor- `mally engaged are formed and disposed as cam-element 101 andy these normally disengaged are formed and disposed as cam elements 102 to 107 inclusive, and in order that the spring element mayact, those engaged and no others are rotated, but when any one or more of those normally disengagedare rotated the spring releasing means cannot act. Furthermore if one or only part o'f the cam elements normally engaged in any combination rotate and not all, yet those not rotating still engage the spring releasing means and prevent it from acting.

The matrix release proper, consists oit a pawl as 1201 of the series 1201 to 1290. These are mountedupon a rod, 1109 held upon the magazine 100. The pawl comprises a Weighted extension 1201a7whicl1 normally engages the earl of the matrix first tobe ejected and is normally held in engagement therewith by the weighted portion 1201i". Said pawl has an arm 1201c which is normally disengaged from the matrix next to the first matrix, but when actuated by the arm 1001 of the spring releasing member 1001 it is lowered so as to contact with the toe of the second matrix and at the same time the extension 1201il is' disengaged from the ear of the first matrix so that the first matrix is released and the impact of the arm 1201C upon the toe ot' the second matrix forcibly drives the second. matrix forward against the lirst matrix which is thus ejected from the channel of the magazine. 'Allhere is an extension 1201d upon the arm 1201c of said paWl 1201 Which terms an inclined plane against which the ear ot the second matrix will impinge When the said arm 1201c is lowered in the manner del, scribed, and thus the torce exerted by the Weight of the matrices in the channel against the second matrix Will cause the ear ot the second matrix to impinge against and elevate the arm 1201d and restore the extension .i 1201rb to the normal position and thereby en gage the ear of the second matrix as it moves into the position of the lirst matrix in readiness to be ejected. rlhe Weighted end 1201h of the pawl 1201 aids in restorino the paWl to 1 its normal position in case the Weight oi the extremely thin matrices in a channel does not aitord sufficient pressure to lift the said arm 1201c and insure the return of the extension-1201" to its normal position so as to engage the ear of the lirst matrix.

The arm 1001n ot the spring releasing member 1001 serves merely to actuate the said pavvl 1201 and is instantly restored to its normal position by the rotating cam rods and cam elements thereof and the paivl 1201 is automatically restored to its normal position by said Weighted portion 1201a and by the pressure of the matrices in the channel in the manner above described.

'lhere are shown in the drawings sixty-one keys. lachY ot said keys actuates one otl the key Weights, which are numbered from 1 to 01, consecutively trom lett to right. The key weight shown in Fig. 2 is numbered 19, and is actuated by tne key carrying the asterisk, :is shown in the keyboard layout in Fig. 1, and indicated as key lever 19.

llie key weights shown in Figs. 2 and 5 are oi" a inodiiied torni, all being of the same shape as though cast trom one mold or cut by one die. Each key Weight, as 19, has an upper extension, as 19h, and a lower extension, as 19a, which are held in suitable guides secured to the trame 300 ot the keyboard y mechanism. Each key Weight has a series of recesses, 19, 19, 19e, 19t. 19%' and 19h, and the rec 19C ot key Weight 19 is engaged by the key lever 19. Accordingly each key lever engages in a recess of one of the key Weights iloscribed. @n the key Weights, as 19, there is a plurality ot' fingers or extensions designated .193, 19-H. 191, 193V, 19-V, 193, 195m, 19N@ The said extensions are adapted for engaging; the rocking; blades numbered 301 to 309 inclusive in the manner deszribed in another part of the specitication, in various combinations. Said key weights are also de* scribed and shown in n'iy pending' application, i'crial l'o. 39,1

lo Figi: 10 is shown a ii'iodilied torni ot the iey Weights in which the fingers or extensions are removably held thereon. The key Weight is designated as `W1 and the extensions are numbered from 1 to 'l'. `llhen using this torni ot t ie key Weight, the proper connections to actuate the required combinations of rocking blades may be obtained by removing from a weight such lingers or extensions as it is not desired to use. Thus, it extensions 1, 3, and t3 are removed, rocking blades correspondinpg` with extensions 1', 3, and ti, Will never be actuated by the Weights trom which they are removed. lilith this form ot key weight, the construction of the blades may be much f-:implilied and any particular key Weight may be so changed by changing; the extensions thercot so as to actuate a diilierent combination ot rocking` blades.

lt will be obvious that the rocking` blades that are not shiitable may be plain blades that are not indented. When this form ot l'ceyvveight is used the form oi' the shiftable blades may be much less simple than when the keyuf'eights with fixed extensions are employed.

@ne form ot means for locking the kev weights is shown in Fig. 2 in dot-ted lines and in 3 in solid lines. A shoulder, 19j, is provided upon each ot said key Weights, and a semicylindrical bar 300X, is revolublyY held thereabove, normally in a disengaged position, and in cross section being` horizontally disposed, as shown in Figs. 2 and 3. llVhen it is desired to lock the key weights againstmovement the said bar 300 is turned by means not shown, 90 degrees or more that the cylindrical surface engages the shoulders, as 19j, ot all the keyweights and prevents movement thereof.

ln Figures 4i and 5 l have shown the preferred form of my locking means, described hereinafter.

Referring' to 5, 309 indicates the locking member correspondingi with the blade 108 in Fig 12 ot the drawings also shown in Fig. 2. Yl'he blade `is rockingly held in contact with the key Weight extension 19W, and is movable with each movement otany oi the Weights, being a solid blade Without any notches therein. Said `blade 308 is normally held by a spring- 308 in the position shown in Fig. 5 but may be shifted to the lett so that the paWl 308b will engage the recess 309C in the plate 309i. The shiiit is made by the cam 808e, which is rotatably held upon the extension of said blade, the movement being` imparted by the button 308f. Said cam engages the member 308(-r Which is keyed to the extension ot said blade and has a lug, 308g2 which impinges against a lug' 30811 so it cannot rotate. but is free to move laterally to the lett and thus bringthe pavvl 808" into the recess 308 so that the blade cannot be moved by the Weight, thus a lock is provided, which pre- Cil vents the niovement of any key of the keyboard.

In my previous application hereinbefore mentioned, I have shown and described shifting blades, whereby I am enabled to increase the number of combinations obtainable witha limited number of blades; In this application I 4employ the same principle, but the shifting mechanism herein shown is of a modified form, and is considered herein as the preferred form thereof.

Two forms of shifting mechanism are shown in this application. In Fig. l2 the shifting mechanism is similar to that shown in my before mentioned previous applica-v tion.

The rocking blades 306 and 307 are shiftable in their bearings. They are held normally at the extreme right` by means of springs 306 and 307D, which vengage collar members 306a, 30666, and 307, The said rocking blades are moved to the left when desired, by key levers 7c and 7.212, portions of which are shown. The movement is adj usted by means of set screws, as 306c and 307, held in the support 300a.

The key lever 7c is adapted for shifting both blades 306 and 307, while the key lever 7512 is adapted to move but one blade, 306.

The preferred form of my shifting mechanism is shown in Figs. l, 2, 3, 6 and 7 of the drawings. The blades 306 and 307 may be shifted, as follows: Upon the blade 306 is rigidly secured a bearing 306a having a lug 306b shown in Fig. 7 which is disposed between the arms of a substantially U-shaped lever 306C held upon a rod V3061. A spring 306e normally holds said shifting blade 306 in its normal position at the extreme right.

Upon the blade 307 is rigidly held a bearing 307a having an extension 307a2 slidably engaging the extension of the blade 306. On the bearing 307a is a lug 307b disposed between the arms of a substantially U-shaped lever 307D held upon the rod 3071, and a spring 307e holds said blade 307 normally at the eXtreme right. Set screws 306t and 307t afford adjustment for said blades and suitable lock nuts as 306g and 307g are provided to secure the set screws in the desired position. vvIVlien the blades are held in their normal position shifted to the right, similar setscrew and lock nuts to secure them may be provided at the opposite ends of the shiftable blades, but these are not shown in Fig. 5 of drawings. But it willI be obvious that by the means described perfect adjustment of the position of the shifting blades can be obtained. It is contemplated that similar adjustment may be provided for the other blades which are not shiftable, to insure perfect adjustment of the notches thereof with the extensions of the key weights, should refinement of adjustment prove necessary in the practice of my invention.

To actuate the said shifting means, rocking keys 306h and 307h are provided upon the rods 306d and 307*1 said rocking keys are rigidly held upon said rods and serve to move the U-shaped leve-rs as 306C and 307C. Pawls 306i and 307i engage shoulders as 306j and'307j upon spring members 306k and 307k, (see Fig. 6). Thus by pressing the button at the right of keyV 307h the pawl depresses the spring by cam action and forces it to the left of the shoulder 3071. The action is the same if it is desired to shift the blade 306. In Figs. 3, 6 and 7, the parts are shown in the shifted position and both of the blades are shifted to the extreme left. stated the springs normally hold the shiftable blades in their extreme position at the right. It is designed to move one of the blades or both of them to the left or shifted position by touching a single'key or single operation; or when both are in the shifted position to reverse the operation and restore by a single operation, one or both of said blades to their normal position, that is by touching` a single key.

This object is attained in the manner described as follows: In Fig. 7 the blades being in the shifted position, that is, to the left; blade 307 may be restored to the normal position by depressing the key designated as S C rocking key 3071. For this purpose the lever 307c moves the bearing 307a to the right and 'the spring restores the blade 307 to its Ynormal position. Blade 306 remains in the shifted position until key L C of rocking key 306h is depressed when the lever 306C throws the bearing 306 to the right andrestores the blade to its normal position. But if in the first place it is desired to restore both blades 306 and 307 to the normal position, this may be done by depressing key button L C of rocking key 306h and then both of the blades 306 and 307 are restored simultaneously to the normal position,by the pressure of the bearing 306 against the extension arm 307m of the bearing 307, thus throwing the blade 307 to the right with the blade 306.

'To shift the blade from the normal position the action is reversed and the key buttons on the left of the rocking keys are actuated. It is possible to shift the blades singly if the left key button of rocking pawl 306h is depressed, and then the left key button of rocking key 30711 is depressed; but to shift both at once to the left the left key button of-rocking key 307h is depressed and this brings the extension 307u2 of bearing 307a into action so that it bears against the bearing 306a on the blade 306 and both blades irfe thereby shifted simultaneously to the In Fig. 12 a modified form of the shifting means is shown, whereby the shiftable blades may be shifted singly or simultaneously, as

As above hereinbefore described, but the shifting keys are designed upon principles shown in my before mentiond previous application.

To facilitate the work of the examiner a table has been prepared same being hereto annerechand designated rfable l, serving to explain in detail the method and means by which the keys of the keyboard mechanism, control the releases for corresponding matrices in the magazine of the linotype machine and which sets forth fully the various combinations of the parts by which the characters of the standard linotype machine may be released from the magazine combination.

'l`lie said table is arrano'ed in alphabetic order, each letter is considered in three forms, and the data each et said. forms set forth in three lines. rl"he characters of the keys giyen in the lirst column.

A `'lhe number of the keys are given in the second column. i

he irst letter7 a is considered, lirst as lower case, second as a small capital and third as a capitaL Each `letter of the alphabet considoredin the same manner.

The number of the key in its numerical order from left? to right is indicated by the numbers in the second column, as shown in @Fig l of the drawings.` i

lhe next seven columns show the functioning of the sevenblades of the keyboard mechanisinand show which ot' the blades act for .the releasalof each letter or character. By `lollowing the movement through the transmission mechanism to the magazine unit, it is possible by the aid of this table to ascertain which cam rods act, and which spring releasing members are actuated and from which channel the matrices will beV released when a particular key is depressed by the operator. i

The last column in the table contains the number of the channel from which the matrix will be discharged when the key` controlling it is actuated. Y Y i 'lllie columns numbered `from 301i to 307 contain ciphers and Xs The ciphers indicate that there is no, contact oi' a w it extension lwith a blade and the Xs indinte that the weight contacts with the blade and that blade is not cut away or indented at the point where the weight corresponding with the number of the key in the second column is in apposition thereto.

For example lower case a is obtained by the a key, (key No, l0- 1d column). Key 10 actuates blades 303 and "304 for lower case a, This is indicated by the rs in the first line of the table, at said colums 303 and 304C. The ciphersin. columns marred 301` 302, 305, 306 and 307 in the iirstline of the table showthat only blades303 and 304 are actuated 'ior releasing lowercase a' from the magazine. rlhe last cob-nn indi` entes that the lowercase a mat. K will be released from the 3rd channel of the magazine.

By reference to the layout of the keyboard in Fig. l, the character of the key will be found on each key and the numerical order or position or' the keys employed in the secw ond column olI 'lable l, is above the upper left corner of the key button.

By referring to Figs. ll and l2, the table may be further explained. ln `Fig. ll, the `'ertioal lines numbered 'from l to 90 indicate the number of the channels of a standard magazine, and the characters thereunder the character' ot' the matrices in the respective channels.` lt will be observed that two characters occur under some of said vertical lines which indicates that two letter matrices are employed for such channels. The circles at the intersection of the said vertical lines numbered rom l `to 90 and the broken horizontal lines numbered 101 to 107 inclusive indicate the cam elements which act in order to release the matrix from the channel corresponding with the line with a given number. Thus lower case Fa, is carried in channel number 3, see Fig. 1l, and the cam elements of cant rods 303 and 304, when acting simultaneously and while no other cam rods are actuated will actuate the `spring' releasing member 1003 andthereby actuate the pawl 1203 and eject the matrix for lower case a. y

Referring to Fig. l2 of the drawings, it will beseen that` a plurality o'f-,blades`v30l to 307 are shown. Each blade` has indenta tions and across said blades vertical dotted lines are drawn which numbered from l to Slatthe upper part of the ligure.` 'llhese lines indicate the position of the key weights, all of which `are alike numbering` 6l in all. rlhe characters on the keys by which the` respective key weights are actuated are shown above the numbers designating the vertical dotted lines, and the indentations in the blades, 301 to 307, show the recesaesin the blades and the extensions thereof; the cesses indicating that where there is a rerl as.. as dotted line 10S, A key, there are rccesss in all blades but and 304, so when `the key weight number l0is actuated by key A the extensions of said keyweigh which are seven in number can engage only blades 303 and 304, because the othe blades as 301. 302, 305, 306 and 307 are all recessed at dotted line 105 and character Afb ThisA corresponds with the eXplanation-given ot' the table to which reference may now be had to check up the method, rlhe same riiles apply to each letter or character of the keyboard, and the operation maybe checked up from the said Table l, 'and Figures l, ll and l?. of the drawings.

A novel method of releasing ligatures is provided, whereby the operator, may release the ligatures of, fl, ill, ae, ce, ii, and nl l of the keyboard,

3y touching the two le in the ligature, thus affecting a combination which will release the ligature desired from the channel in which it is carried. These are also shown in Table 1, and may be checked up with the drawings in the manner hereinbefore described.

The numbers at the right of the key buttons in Fig. 1 indicate the channels from which the matrices will be released when the key is employed, and indicate the difference when the shiftingl blades306 and 307 are shifted from the normal.

It will be seen that for all the letters of the alphabet but X and z the same key may be used, for three operations, viz.: to release lower case letters or matrices, small capital matrices and capital letter matrices.

Vhen the shifting blades are both in normal position (see Table 1), lower case a is released from channel 3 of the magazine, and only blades 303 andV 304'are actuated. Compare Fig. 12, line 10s,'key character A and it will be seen that the blades 306 and 307 are recessed when in their normal position, so that the extensions on weight l0 will not engage the said blades 306 and 307, but` will only engage the blades 303 and 304 aforesaid. The uppermost number at, the right of key A indicates the channel from which 'lower case a is released, when the shifting blades 306 and 307 are in their normal position.

The third number at the right of key A i indicates theA channel'from which a capital A will be released when both ofthe shifting blades 306 and 307 are shifted. Compare with Fig. 11, in which capital A occurs at the vertical line number 63, the third number at the right of the key A is 63 and from channel 63, v(seeFig. 11, and Table 1) the capital A matrix .is released. To release capitals key button C of the rocking key 307 is depressed which shifts both of the shift blades 306 and 307 as set forth.

-The second number at the right of the letter keys indicates the number ofthe magazine channel from which small capitals are released. Again taking the letter A for example; the second number at the right of the key button A is 39, and by reference to Fig. 11, itwill be seen that the small capital A is on the line numbered 39. (See also Table 1 last column).

By reference to the said table, line 2, thereof, under the blade number 306, it will be seen thatthere is an x which indicates that shift blade 306 is actuated by key number 10, (see column 2 of Table l). For all small capitals only one of said shift blades is used, i. e., shi-ft blade No. 306. Thus small capitals are obtained by the letter key of the small capital required when blade 306 alone is shifted. This is accomplished by depressing the key-buttonpmarked S C of rocking key 3061.

Referring to Table 1, it will be seen that there is but one channel number (last column) for all characters but the letters of the alphabet, This is because the matrices therefor are found in but one style, there being no capitals or small capitals thereof; while each of the letters of the alphabet must be supplied in three styles, as lower case, small capitals and capitals. Therefore there must be three channels for each letter, but one channel only is required for numbers, trade signs, punctuation marks, points &c. See Fig. 11.

In Figure 11 is shown the characters on the matrices in the magazine channels, numbered 0, l to 90, making 91 in all; the first channel, designated as 0, being the duplicate e channel.

In this figure the first line of characters below the diagram represent the characters that are cast whenV the matrices are in the lower or ordinary position. The characters in the linebelow represent the characters that are cast when the matrices are in the upper or auxiliary position, this being-the standard arrangement of the small capitals in American line-casting machines, known to those skilledl in the art, and the only one in general use in this country. Other arrangements, as for instance, the English, may be utilized, however, without departure from the scope of my invention.. These secondary characters are positioned by duplex rails in the assembling and casting mechanisms which are old in the art and 'do not form apart of the present invention; their use is known by all operators.

The combinations of the blades for the last mentioned characters andthe combinations for the cam rods of the magazine are such that there is no change affecting these characters when either shift blade 306 or 307, or both of these are shifted, but Whenever the character key thereof is actuated the corrcy sponding matrix of the magazine is discharged-from its respective channel of the magazine.

For obtaining ligatures from the magazine no shift is required; it will be seen by referring to Table 1, that such characters are obtained by depressing two keys of the keyboard simultaneously, and in this manner the coinbination required is obtained and the matrix carrying two letters in a ligature. For example, the ligature ae is desired. It is found in column 89, (see Fig. 11). It is obtained by action of cam rods 3 and 4 required for a and cam rod 1 required for e. (See vertical line 1 for e broken line 101, Fig. 11, and Vertical line 3 for a broken lines 303 and 304, Fig. 11). By touching the two keys A and E at the same time, a different combination is'controlled, and cam rods 101, 103 and 104, act to release a ligature matrix for fromV magazine channel 88. See
